HPE 64GB 2933MHz DDR4 PC4-23466 ECC Registered CL21 288-Pin Load Reduced DIMM 1.2V Quad Rank x4 Memory Module – P03054-091

HPE 64GB DDR4-2933 ECC Load Reduced DIMM — P03054-091

The HPE P03054-091 is a 64GB DDR4-2933 (PC4-23466) ECC Load Reduced DIMM carrying an HPE factory/OEM configuration suffix, built for HPE ProLiant Gen10 servers. Sharing the same quad-rank 4Rx4 architecture and 1.2V, CL21 specifications as the P00926-B21 option kit, it is the factory-integrated procurement variant for this high-density LRDIMM.

Key Features

• 64GB DDR4-2933 LRDIMM factory variant — functionally identical to P00926-B21 option kit
• Load-reduced buffer for maximum memory channel population density in Gen10 servers
• 2933MHz (PC4-23466) ECC-protected bandwidth for Xeon Scalable Cascade Lake platforms
• 1.2V low-voltage quad-rank design for energy-efficient high-density memory deployment

Frequently Asked Questions

What does the -091 suffix mean on HPE part numbers?

The -091 suffix denotes an HPE factory/OEM configuration variant, distinct from the -B21 option kit and -001 spare part designations. The hardware is functionally equivalent to P00926-B21.

Is P03054-091 interchangeable with P00926-B21?

Yes — both are HPE 64GB DDR4-2933 4Rx4 ECC LRDIMM modules for ProLiant Gen10 with identical specifications. They are functionally interchangeable in supported configurations.

What is the difference between P03054-091 and P03054-791?

P03054-791 is an RDIMM while P03054-091 is an LRDIMM — both are 64GB DDR4-2933 for Gen10, but the buffer type differs. Verify your server”s supported DIMM types before mixing or substituting.

The HPE P03054-091 64GB DDR4-2933 LRDIMM is the factory-configured variant for HPE ProLiant Gen10 high-density memory deployments. Get it in stock today at a competitive price.
